Application and May 27,

To all whom it may concern Be it known that I, Guscmvn ANTOINE Rn- NAULT, maker, a citizen of the French Rep ublic, residing at Paris, 37 Rue Reaumur,

rance, have invented certain new and useful Improvements in Clasping Devices for Articles of Apparel; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a simple and convenient means for temporarily securing together parts of various articles of jewelry, such as chains, fobs, cuff links and the like.

Certain preferred forms of the invention are illustrated in the accompanying draw ings wherein Figure 1 shows the male and female portions of a typical form in plan view, Fig. 2 is a transverse sectional view of the part O in Fig.1, Fig. 3 is a view partly in plan and partly in section of the male member of a complete practical fastening made in accordance with the inventiomFig. 4 is a plan view ofthelower plate of said malemember, Fig. 5 is a. plan view of a female member adapted for use with the male member shown inFigs. 3 and 4, and Figs.

6 and 7 are plan views of the male and female members of a modified form.

. typical flat member A having a non-circular open- C will remain fastened together.

into re istry with the opening The general principle of the invention is y exemplified inFigs. 1 and 2. If a in 13 (preferably oblong) is fastened to one en of a chain E and the opposite end of'the chain is furnished with a button or plate C having such a form in plan as permits it to pass through the opening B in one angular osition but not in another, the parts. A and become respectively the female and the male members of a ty ical fastening embodying the principle 0 this invention.

It will usually be preferable, of course, to make C of the same shape in plan as the elon ated. opening 13 and just a little smaller,sothat it will pass through easily. Having been passed through, the part 0 can beturned into the position shown in dotted lines in Fig. 1, and, if held in this position, the two parts secured respectively to A and To unfasten them it is only necessary to bring G V The part C can e given almost any desired shape in cross section; as, for instance, the form 1919. Serial No. 300,203.

shown in Fig. 2. The only essential point in this connection is that the bottom shall be of itfOI'Ill to permit rotation of the part C over the female member A. A flat surface here will usually be adopted.

Figs. 3 and 4 illustrate one practical form in which the above principles can be carried out.

The male member comprises a gem a mounted upon a flat plate 6, constituting a button which is provided with a pivot c, and having fastened thereto a fiat guard-plate cl preferably cut out as shown at e (for lightness) leaving a middle rib f. This rib has an opening g through which passes the pivot pin 0 with a revoluble fit. Beneath the plate 03, a small rivet or nut it is fixed to the end of the pivot pin 0, and a ratchet wheel i with wide shallow rounded teeth is welded or brazed onto the pivot pin so as to lie fiat against the guard-plate. d. Two spring pawls j and is are fixed each at one of its ends Z and m to the rib while their free ends rest on the ratchet pinion i, so as to prevent accidental turning of the button, while permitting it to be turned purposely by the fingers.

The female member of the clasp or fastening comprises a plate 0 having an elongated opening a and is fixed to the chain p or other part to be fastened. The button a is preferably of the same shape as the opening nand a little smaller, so that it can be pushed through this opening and then turned into the desired locking position, in which osition it will be held by the ratchet z and t e pawls j and In. In this position,

the plate n will occupy the space between the button a and plate 03, and thereforethe space '7' between these parts should be a little greater than the thickness of the plate 0.

This last named plate, and the button co operating with it, may be given a great vadescribed, a female member having a noneircular opening, and a inale melnber comprising aoguard-piate, 2t button adapted to pass through saidvopening in one angular I position but not in another, said button being revolub'ly mounted on said guard-plate, and means tending to prevent the accidental turning of said button on said guardplate, the button on the male member hav-
